在每个主干同步请求中发送令牌 [英] Send token with every backbone sync request

问题描述

我的PHP api要求在我的前端Backbone应用程序的每个请求中提交用户令牌，以确保用户...

My PHP api requires a user token be submitted with every request from my front-end Backbone app to make sure the user...

1. 处于活动状态
2. 具有访问资源的权限

在Backbone中进行设置的最简单方法是什么?我猜唯一的方法是覆盖Backbone.sync，但是代码是什么样的呢?首选CoffeeScript.

What is the easiest way to set this up in Backbone? I am guessing the only way is to overwrite Backbone.sync, but what would the code look like? CoffeeScript preferred.

还有两件事
1.如果我得到一个403: Access Forbidden Error
，我想将用户重定向到/login. 2.启动应用程序时，我从localStorage中提取了包含令牌的用户模型.
3.我有一个baseModel和baseCollection，所有模型/集合都来自

Two more things
1. I would like to redirect the user to /login if I get a 403: Access Forbidden Error
2. I pull the user model which includes the token from localStorage when the app is bootstrapped
3. I have a baseModel and baseCollection which all models / collections come from

推荐答案

您可以执行以下操作:

var _sync = Backbone.sync;
Backbone.sync = function(method, model, options) {

    if( model && (method === 'create' || method === 'update' || method === 'patch') ) {
        options.contentType = 'application/json';
        options.data = JSON.stringify(options.attrs || model.toJSON());
    }

    _.extend( options.data, {
        "access_token": "some-token"
    });

    return _sync.call( this, method, model, options );
}

然后仅监听fetch/save方法的失败事件即可将用户重定向到/login

And just listen for the fail event of fetch/save method to redirect a user to /login

model.fetch().fail( /* redirect */ )
